Subject: git-mailinfo fixes for patch munging
X-Git-Tag: v1.5.1~12
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=86747c132b87fc97bbb134baaffe9ecc12c5a90d;p=git.git

git-mailinfo fixes for patch munging

Don't translate the patch to UTF-8, instead preserve the data as
is.  This also reverts a test case that was included in the
original patch series.

Also allow overwriting the authorship and title information we
gather from RFC2822 mail headers with additional in-body
headers, which was pointed out by Linus.
